My local Garrett distributor/builder didn't offer a T3 exhaust housing as an option for building a GT30 for our cars.
ATP Turbo is listing a new turbo that is supposed to cater to the 4 cyl. market and have better spool up characteristics than the GT30.
Model GT3017R comes with a T3 style turbine housing with T3 inlet. Compressor housing is sized the same as a T04E with a 2" oulet. 2.75" or 4" inlet are available.
Edman, I wonder if your turbo is based on this turbo?
Check it out.

That weird that he told you that???
Because the GT30R & GT35R come factory with the t3 style inlet flange.
Its even written in the catalog.
My turbo is kinda like the on from ATP exept i have a 76mm wheel and they have a 71mm wheel.

Raj,
Don't know where you're seeing "your" turbo being listed for $3 grand, but the Garrett distributor I've dealt with (locally) is the same one Cervelli used for his GT turbos when he was here in AZ. You picked up your turbo set up from Cervelli right?
The GT30R Thomas described (according to the catalogue) is the turbo I inquired about - the turbo you apparently have. I was given a $1400 retail price, so if you're seeing this turbo being listed for $3 grand - I'd say somone is looking to rip someone off!

Hi Edman,
Hey I just bought tghe same adaptors that
you're using for the for the installation.
Sorry to bother you again but I need some
more tips from you.
1. How much space is left between the flange
& the engine mount after mounting the turbo ?
2. Once you set the correct height of the turbo,
do you use a lock nut to lock the turbo to the
flange ?
3. What do you use to seal the threads from oil
leaks
Thanks again Edman

Hello Edman!
Is your GT30 57 mm (2,24") at the compressor intake, (57 mm wheel)? I really want to know because I´v heard that the "Ported Shroud" house only can have Trim 52, a wheel of 55 mm (2,16"). I´m planning to move up a bit in turbo size myself from that I have today which is similar to the Garret 3071R.

Corleone,
I'm not sure about the wheel size on that end, i will mesure the induser this weekend and post it.
But it supposed to be a 56trim and 76.2mm major.
J Chen
I'm happy to help you, if you want you could e-mail me also.
1) I actually bottom out the fitting on the mount to get the max clearance.
And i even shave down the mount until i couldn't see the hole for the o-ring. To get the correct height its a trile and error thing. By sitting the turbo on it and seing if the intake can seat flat.
Whatch out for the turbine housing going too close to the mount.
2) No need for a lock nut. Try to get it all to fit with the adapter bolted tight on the mount so you don't get a leak.
You will need to use a tap to make the right threads in the mount.
The threads is what seal it.
Also be prepared to shave the extra threads sticking out on small end of the adapter that goes onto the oil flange. So that you get the flange seated as low as required. This is what i used to adjust the height i wanted the turbo at.
Ideally get a steel flange about 3/8'' thick. and tap it to the thread on the small side of the adapter.
Make sure the flange is straight so that it seal good to the bottom of the turbo. Use a gasket and a bit of silicone on both side to help seal it if its not perfectly straight.
Don't forget that you must also align the turbo so that you can fit the crossover and downpipe. The angle is about at the 11 o clock position when you are in the fromt of the car.
If you have more question.
Just ask.

Hi Edman,
Thank you very much for all the
advices. Theres one thing that
still bugs me. Since you bottom
out, how did you bolt the turbo
the flange ? Would'nt it be better
to shave the engine mount a little
more to gain clearance ?
I'm actually toying with the idea of
welding a machined adaptor to the
CHRA but thoughts of killing the BB's
with so much heat !!!!!!! Hmmm
maybe I can water cool the CHRA
while welding. What do you think ?

Yes it does get thight in their to bolt up the turbo.
That why i shave the mount and made grooves in the top see picture.
You can see the shaving i did to completelly eliminate the holes from the factory flange.
But you should try a few thing to see what you think work best for you.
This is a little drawing i did real fast to show what i did.

Bottom line if the mount.
Top line is the flange to bolt to the turbo.
Blue squres are the bolts.
Also the reason i did it this way is because it was simple. But i tought that if it did not work i was going to buil a custom turbo mount. And use a N/A insteed.
I aslo suggest you not to weld anything on the turbo.
Their are other option.

Edman, I'm with you. Raj, what are you trying to say??
All I know is that I will trust the product and pricing being quoted directly from an Authorized Garrett GT Performance Distributor (listed on the online Gattett catalog) before looking at supposedly the same product being offered by a different turbo company at twice the price!!
Who do you think has more authority in regards to pricing and options of this turbo - Turbonetics or Garrett?
Raj, you mentioned that the description that Thomas made about your turbo was exactly right (quoting the catalog,) yet the description of your turbo on the Turbonetics link shows your GT30 to have a .70 A/R compressor housing instead of the .60 A/R that the Garrett lists in the catalog for the GT30R.
So, who has the real GT30 then? You or Edman?
In the end, I'd rather deal directly with Garrett instead of a vendor of Garrett who is dramatically marking up the price for what seems to be the same product.
I don't know if this has anything to do with Turbonetics pricing, but the Garrett dealer told me that Garrett frowns upon doing business with Turbonetics because they've made knock-off's of Garrett products and sold these products under the Turbonetics name. I don't know how much of this is truth, but it is what I was told.
